MEANS FOR FLUSHING SEWERS.

SPECIFICATION forming part of Letters Patent No. 394,166, dated December 11, 1888.

Application filed September 13, 1888- Serial 110,285,326. (No model.)

To all whom it may concern.-

Be it known that 1, THADDEUS GALVIN, a citizen of the United States, residing at Detroit, county of \Vayne, State of Michigan,

have invented a certain new and useful Improvement ,in M cans for Flushing Sewers; and I declare the following to be a full, clear, and exact description of the invention, such will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

In the drawings, Figure 1 is a plan view illustrating my invention. Fig. 2 is a longi tudinal sectional view more particularly illustrating the features of construction. Fig. 3 is a cross-sectional view. Fig. 4: represents a variation in which th e water-conduit is formed integral. with a sewer-pipe along its upper portion. Fig. 5 is a separate view of one of the nipples or leaders.

It is the purpose of my invention to provide a sewer or sewer-pipe with a water-supply pipe for flushing the same, said water-supply pipe located along the top on the outside of the sewer-pipe and communicating therewith by nipples or leaders passed therefrom in through the wall of the sewer or pipe; also, in providing said nipples or leaders with perforations at the front and rear adjacent to its end, and also at the sides, if desired,whereby the water is discharged in the several directions to wash down and clear away matter which may collect within the pipes or sewers.

My invention consists, also, in other novel features of construction, as will be more particularly specified in the claims.

In carrying out my invention, A represents a sewer or sewer-pipe.

B is a water-supply pipe, which leads along the top of the sewer upon the outside of the same.

B represents nipples or leaders extending from the water-supply pipe through the wall of the sewer or sewer-pipe to the inside thereof. These leaders maybe provided with a through-opening, or the end may be plugged and the leader be provided with orifices I), through which the water may be discharged in sharp jets to the front and rear, and also ,to the sides, if desired.

The operation of this portion of the device is as follows: Sediment having gathered within the sewer or sewer-pipe, water turned 011 through the water-supply. This water, entering through the nipples, is discharged through the jets throughout the whole length of the watcr-pipe, and each jet wears away the sediment at that particular part, and the flow of water quickly reduces the obstruction and operates to thoroughly flush and wash out the sewer. Each said waterpipe is provided with a valve or gate, C, for admitting or shutting olf the water at will. So, also, I prefer to provide each said water-pipe with a trap, D; or, instead of a trap, it inay be simply a plugged pipe leading to the surface of the ground. This is for the purpose of afiording a ready means of diseoverin whether the impediment in the sewer is above or below this particular point. If it is above this point, the sewer being clear at this point, no particular odor would be discovered at this opening. If, however, the impediment was below this point, the odor upon removing the plug or cap would be strong, and so the impediment might be quickly located, and when located could be cleansed by the introduction of water through the corresponding pipe, B. The leaders 13 having been passed through the sewer-pipe or through the wall of the sewer, the spaces about the said leaders are thoroughly stopped, so as to admit of no leakage at these points.

I am aware that it is not new to lead a water-supply pipe of this character upon the interior of a sewer close to its upper wall. It is manifest, however, that in constructions of this character the pipe must be introduced and sustained by brackets or otherwise along the upper wall, and that to accomplish this location of the water-pipe the sewer must needs be of sufficient dimensions for aworkman to pass through it upon the interior. So, also, such a construction practicallyprohibits its use in the large mass of sewer-pipeswhich are rarely of such dimensions as to admit a person through them. Moreover, this construction, whereby the water-pipe is located upon the outside of the sewer, admits of its ready connection with any sewer-pipe or sewer, no matter how long the sewer might have been laid, and affords at all times ready access to the said flushing-pipes by uncovering the sewer.

In making sewer-pipe or sewer-tiles a waterconduit might be formed integral with the same along its upper portion and provided with orifices b at intervals leading into the sewer. Such a construction is shown in the variation in Fig. 4.

Each of the valves is preferably provided with a box, IE, leading to the surface of the ground to facilitate access thereto.

The trap D is preferably provided with a valve, d,whereby it maybe emptied when it is desired to test for sewer-stench; or the vtrap may be dispensed with entirely, as shown in Fig. 4.

F is another flushing-valve, which may or may not be employed, and if employed is for the-purposeof throwing a large stream intolt-he sewer.

That I claim is -1. The-combination, with a sewer .or sewer- ;pipe,-of a water pipe or conduit -.extending along its top upon the exterior of the same and provided at intervals with nipples or leaders B, extending through the wall of the sewer'or :pipe, andmeans for admitting and cutting off the Water therefrom at will, substantially as described.

2. The combination, with a sewer or sewerpipe, of a water-pipe extending along the top upon the exterior of the same and provided at intervals with nipples or leaders B, said leaders stopped at .theirextremities and provided with lateral orifices b, and valves or gates for admitting water to or cutting it oit from the pipe, substantially as described.

3. The combination, with a sewer and a flushing-pipe, B B, of a gate or valvefor governing the admission of water thereto, and a testing pipeor trap, D, substantially as and for the purposes described.

4. The combination, with ,a sewer pipe or tile, oi: a water-conduit formed in its upper
